The physical properties of biological molecules will be explained using firstly examples from simple chemical processes and then the concepts extended to large biological molecules.
Areas to be discussed include energy changes during reactions and how such energetics help to determine the principles of chemical equilibria and limitations of yield etc. are linked with such considerations.
The basic understanding of the rates of chemical and biological reactions will lead on to a simple consideration of the importance of enzymes in biological processes. The concepts of pH, acids and bases, buffers will be explained and their importance in the properties of biological molecules such as amino acids and natural bases emphasised.
A simple discussion of radioactivity, isotopes, radioactive emissions and safety and health aspects of handling isotopes will be given, if there is time.
Audio-visual and computer based packages will be used to extend the knowledge and depth of the lecture course and provide the basis for the continual assessment of the course.
